another fix exists but this one is easier to install and is not affected by DCS updates so you dont have to reinstall it after every update.
how to install:
with JSGME/OVGME
or
If you dont have JSGME/OVGME:
put the files
(F5E-CPT-FLOOR-01.dds, F5E-CPT-MAIN-01.dds, F5E-CPT-PARTS-01.dds, F5E-CPT-PARTS-02.dds, F5E-CPT-SEAT-01.dds, F5E-CPT-TOP-01.dds ) in your game folder/bazar/temptextures.
